The resistance of a platinum wire is to be calibrated for low-temperature measurements. A platinum wire with resistance 1.00 at 20.0°C is immersed in liquid nitrogen at 77 K (-196°C). If the temperature response of the platinum wire is linear, what is the expected resistance of the platinum wire at -196°C? (a platinum = 3.92 x 10-3/°C) |
